Very nice!
Very nice! Great details and clarity.
Good catch too! I've not seen spiketails in Guelph yet.

 
Thanks Kaylee.
Nice to meet another colleague from Ontario. Yes, the spiketail was a surprising find indeed. I've been doing lots of searching for ode naiads.

 
Equipment question
Hello again Stephen,
Spiketail season again and come across your photos once again. :) I wanted to ask what equipment you used to take the close up photos of the jaws. They are wonderful photos. It looks like an under the microscope photo but I have had VERY dismal results from any microscope photography I have attempted (but I only have access to a very poor quality microscope).
Thanks,
Kaylee

 
Plastic cup
Kaylee - thanks for the compliment. These are not microscope images. I took a photograph as normal through a plastic cup (the kind used in pet stores for holding beta fish - though any hard, scratch-free plastic should work). The problem with this method is unavoidable peripheral distortion from the container's curvature.

 
Hah, brilliant! Wonderful jo
Hah, brilliant!
Wonderful job! (shows once again its the user as much or more than the fancy equipment that makes the photo) I'll have to try that method in the future.
